STEAM REGENEBATIVE ACCUMULATOR..

Specification of Letters Patent.

Patented May 26, 1914.

Application filed March 13, 1912. Serial No. 683,447.

To all whom it may concern Be it known that I, LEONCE L. BATTU, a citizen 'of the United States, residing in New York, city, county, and State, have invented certain new and useful Improvements in Steam Regenerative Accumulators, of which the following is a full, complete, concise, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to a steam regenerative accumulator installation and has for its object the provision of means whereby exhaust steam from engines or other sources of steam at variable pressure may be brought to a pro-per condition of pressure to render such exhaust steam adaptable for further use, particularly for power purposes, although I do not wish to be limited to the use to which such regenerated steam is put.

One of the objects of my invention is the provision of means whereby a secondary engirls will have a greater range of working pressure than the range of the back pressure on the fluctuating source of steam supply. In accordance with my invention the above result is obtained by making the resistance to the passage of steam from the fluctuating source through the regenerato-r dependent upon the steam pressure in the steam regen-' erator, or, in other words, dependent upon the pressure of the regenerated steam. In practice it is often of considerable importance to prevent the pressure of the fluctuating steam supply source falling below ;a predetermined minimum, atmospheric pressure for instance, and in one embodiment of my invention I employ a regenerator in which there is contained a regenerating medium, such as water, and the steam from the fluctuating source is introduced into said medium at different levels, thereby varying the resistance of steam passage through the regenerator.

My invention consists 1n the novel parts, improvements and combinations here1n vation of the regenerator embodying my invention, A is the source of steam at variable pressure, which can be for instance a steam engine. 7

B is a pipe leading the steam from the source of steam at variable pressure to a steam regenerator IV, shown diagrammati- Cally.

M is a pipe leading from pipe B to regenerator IV. This pipe M discharges steam from source A into the steam chamber of regenerator W. Valve L controlsthe opening of pipe M and is actuated by diaphragm J, which is controlled by the pressure of the steam in R led under diaphragm J by pipe N.

G is a weight used to set valve L at a de sired pressure for its opening.

C is a pipe leading steam from the pipe B mto the regenerator W under the level of the water or other regenerating medium. Openings O in pipe C distribute the steam in the body of water. The flow of steam from pipe C is controlled by a valve E, which is operated by diaphragm F responsive to the pres- 'seen' that pipe B is prolonged by pipe I) which enters regenerator IV at a lower level than pipe C and which is adapted by means of holes P to discharge steam into liquid X contained in regenerator IV. The pipe Q is a channel leading steam from steam cham* ber R of regenerator IV into steam turbine S, which in my drawing is shown equipped with a condenser T.

It is understood that. valves E and L are so adjusted that E will open at a lower pressure in Rthan is required to open L. It will be seen, therefore, that by properly setting valves L and E the steam discharged by the source of steam at variable pressure can be made to flow entirely above the liquid X of regenerator IV, or can be made to flow through pipe C as soon as the pressure in the steam chamber R becomes low enough to close valve L and that when the pressure in It is low enough to have closed successively valves L and E, the steam will be directed into liquid X at the lower level through pipes B and D which are unobstructed at all times.

In view of what I have described above, it will be seen that the source of steam at the steam di'schargedby source A through.

water X contained in the regenerator IV will beequal to the head of liquid above the holes P; On the other hand, this increased resistance is due to a lowering of pressure in R, which in turn controls valves L and E. The apparatus can therefore be designed in such a way that the pressure on the steam discharged by A can be made'practically constant and limited to any predetermined pressure.

In order to show that my apparatus is well adapted for ranges of pressure reaching a point lower than atmospheric pres sure, I have shown a turbine S equipped with condenser T.

The broad claims to the invention disclosed herein have been made in my copending application, Serial No. 724,280, filed October 7, 1912, the claims in this case including the introduction of the fluctuating steam above the liquid in the regenerator.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a steam regenerator containing liquid, the combination of means for introduoing steam into said regenerator above said liquid and into said liquid at difierent heads, and pressure-controlled means for controlling the introduction of said steam into said regenerator.

2. In a steam regenerator containing liquid, means for introducing the steam to be regenerated into said liquid at different levels, one of which is Zero, and means for selecting the depth of introduction of the steam into said liquid dependent upon the regenerated steam pressure.

3. Asteam regenerator containing a body of liquid, piping directing the steam to be treated above or under the liquid level, a valve controlled by the pressure of the re generated steam selecting automatically the piping through which steam to be treated shall be directed into the regenerator.

4- In a steam regenerator containing a body of liquid, pipes directing steam to be treated above the liquid and at different depths into the liquid, valves controlled by the pressure of the regenerated steam selecting the piping through which the liquid shall be directed into the regenerator, the pipe directing the steam at the lowest depth in the body of liquid being mechanically open.

In witness whereof, I hereunto subscribe my name this 12th day of March, 1912.
